Mapped a network drive to the share in Win 7 and Initially tried testing network performance with built in 10/100 nic (on Ubuntu server) and performance wasn't great. Installed an Intel Gigabit NIC into the PCI express x16 slot and then tried again using the methods you specified in this posting: viewtopic.php?p=7001#p7001.

Write performance

Ran

Code:

ntimer creatfil test1.dat 97657

command three times with different file names and the command ran in a little under 6 seconds (avg. 5.9) which by my calculations equates to 16.9 MB/s.

Read performance

Ran

Code:

ntimer xcopy test1.dat c:\temp

command a few times and average time taken was just over a second (1.1) for a 90MB/s rate.

Just wondering what you think of these results? Planning to use the HP system as a NAS and squeezebox server using the Ubuntu server os fulltime.

Thanks!-Paul

Scott

It's a lot better than an NSLU2, but that's not saying much <g> and in this case the file size is simply not big enough for meangiful results. For a more accurate test you'll want to create something larger that will take closer to a minute (or more) to create. In addition, you'll want to create the file from the client directly on the server share (do not copy or xcopy the file), which will exclude the disk performance of the client system. Finally, if you want to isolate and compare the performance of various server OS, then run the same test on the same server running other OS (e.g different versions of Windows), then compare the file creation results. Let me know what you find. Scott.
